RE: instrument air package
Does the utility air include start-air for big turbines? If so, the package vendor should know of peak short-term demand. How many start over what period?
What utilities are available? 480 vac 60 Hz? Starters included or excluded with the package? PLC to control the sequencing? Common trouble alarms, other monitoring requirements? Offshore paint? What color? You want it when? What documentation? Are there corporate specifications that apply? ... ...
Start with a short list of packagers and review their packages?

RE: instrument air package
I would suggest yes to the dew point analyzer. You don't want water in an IA system.
I would also suggest yes to the PLC. The last IA system we bought came complete with everything on a skid. It worked beautifully. The one we did prior, where we did the PLC programming ourselves, not so good.
I like ihuoma2's idea of separate air receivers for IA and UA. A lot of project managers don't see the need to separate them.
